This means that your fax is only storing into its internal memory and not printing all incoming faxes, therefore it has no more space for more incoming documents, you should print the documents and maybe you'll need to clear the memory, depending on fax machine, this is done automatically when the documents are printed, and of course, set the incoming faxes to print not to store, this feature is supposed to be used only when the fax has no paper to print.

You can receive faxes automatically or manually. If you turn off the Auto Answer option, you must receive faxes manually. If you turn on the Auto Answer option (the default setting), the device automatically answers incoming calls and receives faxes after the number of rings that are specified by the Rings to Answer setting. (The default Rings to Answer setting is five rings.)
If you receive a legal-size fax and the device is not currently set to use legal-size paper, the device reduces the fax so that it fits on the paper that is loaded. If you have disabled the Automatic Reduction feature, the device prints the fax on two pages.
NOTE: If you are copying a document when a fax arrives, the fax is stored in the
device memory until the copying finishes. This can reduce the number of fax pages stored in memory.

You can receive faxes manually from a phone that is:
• Directly connected to the device (on the 2-EXT port)

NOTE: The automatic document feeder must be empty to receive a fax. If there are documents in the ADF, then the device will not be able to receive incoming faxes.

2. Remove any originals from the document feeder tray.

are documents in the document feeder, then receiving the fax will be
unsuccessful.
3. Do one of the following to answer a fax manually:

incoming call before the device answers.

answer incoming calls.

do a quick check on 2 things.
- Copy a document(put a printed page on document feeder and press Copy button) , has the Copy come ok? if copy is also blank that means toner/ink problem, needs to be replaced.

- check with your Fax receive Print settings. is any setting of econo mode/ contrast/brightness Off the track? If found any of such issue then Reset it or put it on average (middle).

Hope this will put your Brother on the track

basically if the fax is well kept, its dialing properties will remain ok. what you need to check is the quality of print out. to test the quality of print out just try to copy a sample document. if your fax is a thermal type, change the paper first before proceeding with copying. if your fax has a menu and help button try pressing the menu first before help for the fax to print a helplist.

press setup on printer select preferences and select default tray as 2 and try making copy and also check while receiving fax and also follow this link http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01096354&cc=us&lc=en&dlc=en&product=1119598&dlc=en&lang=en
